$\large\boxed{\begin{array}{l}\sf a)~\rm\dfrac{x}{4}=\dfrac{9}{3}\\\\\rm \dfrac{x}{4}=3\\\\\rm x=3\cdot4\\\rm x=12\end{array}}$

$\large\boxed{\begin{array}{l}\sf b)~\rm \dfrac{3}{x}=\dfrac{4\div4}{8\div4}\\\\\rm\dfrac{3}{x}=\dfrac{1}{2}\\\\\rm x=2\cdot3\\\rm x=6\end{array}}$

$\large\boxed{\begin{array}{l}\sf c)\\\rm\dfrac{x}{6}=\dfrac{16}{8}\\\\\rm \dfrac{x}{6}=2\\\\\rm x=2\cdot6\\\rm x=12\end{array}}$
